THREAD GUIDE ro-n srrnnine MACHINES.

Application filed November 24,1923. Serial lfTo. 676,752.

To all whom it may concern:

Be it known that I, OTHo citizen of the United States,and resident of lVillimantic, inthe county of Windham and State of Connecticut, have invented certain new and useful Improvementsin Thread Guides for Spinning Machines, of which the following is a specification.

This invention has reference to guides 'for winding or spinning machines, where a thread is drawn from one spool or bobbin and wound upon another spool. A j

The object of the present invention is to provide a thread guide that will have its portion adapted 'to engage a thread of con siderable extent or area, and which member can be readily shifted or adjusted whereby a considerable number of different surfaces can be brought to position for 'en gagement'with the-thread, and by a comparatively'small and simple 'adjust'ment' 'on the support for the guide member.

A further object of'the invention :is to provide a special guide arm to prevent the thread movementaway fromits desired en-' gaging position, and which member'is also made adjustable to be shifted corresponding with the shifting movement of thethread engaging portion. j V r In the accompanying drawing showing one embodiment of my invention,"Figure 1 is a side elevation of the device.

Fig. 2 is a-longitudinal' section. Fig. 3is a transverse 'sec tionf Fig; 4 is a similar view showing'wear in the disc by the thread. Fig: 5 shows the device with the guide or threactretainer, in side elevation;v 1 'Fig. 6 is a transverse section through'the deviceasshown in Fig. 5. In the use of such devices as these,especi= ally where the member that engages the thread is formed of a non-metallic substance such as porcelain, it is found that the'friotion of the thread passing againstthe guide surface will soon wear away'such surface and provide a groove whichbecomes injuribus to the thread; "It' thenb'ecomes necessary to provide a 'fresh' unwo rnsur'face for ment by such adjustment, and without shifting the supporting member.

In the arrangement shown 'hereinI provide a support in the form of a disc or spool 7 that is adjustably carried by a supporting member in the form-of arod or stem 8.

The disc is shown as provided with a comparatively deep annular groove' Q. The disc is provlded wlth a bore 10, into whi'oh projects the end portion 12 of the stem, that is I bentv to extend at a right angle to the stem 8.

This bent portion is passed through the bore I of the spool, and the extremity is. provided Wltll suitable fastening means, such as a nut 13 engaging the screw thread extremity A of the stern. It will be understood that when this nut is tightened-"against the" side face '15 of the spool, the latter will be pressed on the bent portion or the stem until the opposite face'15ofthen 1 111 engage the stem 8.

" Upon loosening the nut'13 thespool v obviously be turned on the'bent stem and a different portion of'the-groove 9 will be brought to the I, path of movement of the thread 6, as 'indicated'in' Figs. 1 3" and 4, where as shown in Fig. 4 the shaded portion 1 represents a worn portion 'of the'spool groove, that by' slightly turning the spool will cause a fresh unworn part to-engage the thread 6', and the nut'13 is again tightened to secure the spool in this position. v

j VVhile such an arrangement would provide a considerable number of adjustments for. the spool on the stem, I preferably provide abutment portions I on the spool for engagement with the stem. As shown the spool on the side 15 is providedwith.aseries of radial grooves 16, of a size to lit the stem 8 tliat is" brought to register therewith as indicated in Fig 2. As shown I provide eight of these radial grooves that will give eight difierent positions of adjustment; for the. spooloniithe stem and which willj'be equally spaced-apart. WVhen any one place becomes wornby the thread 6 the nut13 is loosened and the 'spool slightly moved] to bring thegroove away from thestem 8', and 'then'ithe spool is turned. to bring "an adj acent groove 16 opposite the stem, when the nut is again tightened. 1" Each fresh surfaceofthe spool'grooveiis in the-same posie tion relative to thepath of the thread'fi.

of guide or retainer forthe thread to pre- V vent its getting out of the spool groove. In Figs. oand: 6 I show a guide formed by a rod 20 having a loop 21 adapted to be clamped between the nut 13 and the adjacent face c t-the, spool, as-clearly shown in Fig. 6. Thelend portion 22 of the guide extends transversely across the plane of the spool,

and also that of the stem- 8, asindicated in Fig. 6. This member and the stem 8 will prevent thethread from moving out of the groove; hen the nut is loosened to-adjust the spool on the stem, the guide arm. 22 can also be shifted to retain it in proximity to the stem. The side 15 of the spool may also be provided with a series of radial grooves 23 arranged to engage the stem 20, and which grooves are arranged similar to the grooves 16 on the opposite side. When the spool is shifted on the stem to engage another, groove with the stem, the guide arm is also shifted in a similar manner, to engage the next groove, and will thus maintain its position relative to the supporting stem 8.

It will be noted, by referring to Fig. 5, that the retainer 20 is angularly inclined to the supporting stem S-relatively, so that the extension 22 thereof overlies the supporting stem 8 thereby permitting the ready introduction of thread therein by a sidewise motion. Inorder to accommodate the desired angular relation of the retainer to the supporting stem in the grooves 16 on opposite sides of the guide 7 the said grooves are spacedin staggered relation to each other on opposite sides and they therefore maintain the'retainer and support rod8 in the desired relation.

WhatI claim is:
